Detailed Description

Basic library for AM2301 (DHT21) temperature and humidity sensor.

This library does not use any timers and interrupts to increase speed, only basic pooling mode.

Default pinout

AM2301  STM32Fxxx      Description

VCC     3V3-5V         Supply voltage from 3V3 to 5V
GND     GND            Ground
DATA    User selected  Data line

Data output

Temperature and humidity are returned from sensor in x10 multiplier, so like 55.5% humidity, sensor will return 555 and for 27.3 degrees, sensor will return 273.

Note: This values are also returned from my library, you have to manually convert them (divide by 10) if needed.
